Referring particularly to the accompanying drawings, I0 represents a terminal post of the battery II, which is held in the battery casing by means of the flange I2, and the nut I3, bearing respectively against the lower and upper faces of the top of said battery. Formed in the peripheral face of the upper end portion of the post I0, is groove I4, the purpose of which will be presently explained herein.

Engaged on the post I0 is the conductor terminal, represented as a whole by the numeral I5. This terminal includes the pair of arcuate mem- (Gl. 17e-*1259) :bers I6, `pivotedftogether at one vend lby -means ofthe pin `I"'I,'and` having the ears I8 so spaced 4as'to permitithe `interposition of the apertured Alug ISLof'the'tubular memberf20, within which lthe endof the conductor J20 Eis secured. This "5 lug I-S'also receives the pivotjpiml l therethrough,

Aand. has the projection 22, which-'engages in the I"groovelil dftheipostill), the groove-entering portion of said projection "forminga continuationw of thev ribs of the arcuate'mernbers I"6 In tha-I0 concave 'face fof* eachof thel arcuate members I6 'thereis formed allongitudinally extendingrib 23, `which, whenrthe device is disposed in proper. embracing Irelation toV vthe l `post, enters `the before- 'mentionedgroove I4. 'As clearly seenin the topi'l plan view, `Figure :2, the otherendsof the arcu- 'ate vmembers do not contact, when arranged 4in embracingrelationtothe post. vIntheouter or 'convex-face of eachofthe yarcuate members I6 's-a longitudinal groove 24. A split spring'band520 vr*is engagedfin the-'grooves124,'orithearcuate fmernbers I'Sfto'hold thelatterin embracingengagement Withthepost,'said'spring band having anf'intermediate Veshaped kink 26, and yhaving 'itsfen'dsturned downwardlygas* shown at 2 'I form- 325 ingin'ger meansto" facilitate the removal thereof. In the operation o'f'y the device,` theimembers I 6 V-areswungfapartsiiiiciently'to permit said mem- '1 bers being engaged inf embracing relation #to the battery" post 'I 0, Iwith-the ribs L23 properly seated #30 in the groove I4. The spring band is then slipped or sprung on the members I6, by engaging the outturned ends with said members at opposite sides of the spaces between the ends thereof, and pressing the band inwardly until it embraces the members and lies within the grooves 24. The spring band is of suflicient strength to tightly hold the arcuate members of the clamp in engagement with the post.

Due to the Weight o-f the cable end, which is se- 40 cured within the tubular member 20, Said cable end would sag, resulting in a downward pulling action on the pivotecl portions of the arcuate members I 6, and the tendency of the same to become partly sprung out of their groove engagement with the post, thereby producing a looseness between these members and the post, and the incomplete transmission of current from the battery to the cable. The presence of the projection 22, which is engaged in the said groove, of the post, will prevent this sagging, whereby the parts Will maintain their rm electrical contact with the post. Furthermore, in view of the fact that the arcuate members I6 are pivotally con- Y nected with the projection I9, and such connec- 6B and extending from one side of said member 28v is a lug 29, the outer end of which is provided tion is, of necessity, comparatively loose, the transmission of current, from the battery post to the Wire cable, through the tubular member 20, would be somewhat impaired. Therefore, by reason of the fact that the projection I9 engages directly with the post, and is an integral part of the tubular member, the current will be readily and effectively transmitted to the cable.

In Figure 8 there is shown a modified form of the cable terminal, which includes the tubular portion 28, in the bore of which is adapted tobe secured an end of a wire cable, and formed on with the curved portion 3U, corresponding toan arcuate member I6, of the first form, but in this instance being stationary instead of movable.

The inner portion of the lug 29, adjacent the member 28, is reduced in thickness, as shown at 3|, over Whichis straddled the bifurcated end of the movable jaw 32, a pivot pin 33 being engaged through said jaw and said lug. The exteriors of the stationary jaw 30, and the movable jaw 32 are grooved, as at 34, to receive the spring band 35, which, like the spring band 25, has its ends turned out to provide iinger means to facilitate the removal thereof.

This application is a refiling of that filed March 8, 1932, Serial No. 597,596.

What is claimed is: n

1. A battery connector including a peripherally grooved post, and a conductor terminal having a lateral extensionengaged in said groove of the post, and post embracing members movably supported on said extension, and a spring band embracing said post embracing members, said band having outturned ends forming finger means to facilitate the removal of said band.

2. A battery connector including a peripherally grooved post, and a conductor terminal having a lateral extension engaged in the groove of the post, and post embracing members pivotally carried by said extension, and means for holding the embracing means engaged with the post.

3. A battery connector including a peripherally grooved post, and a conductor terminal having a lateral extension engaged in said groove, post embracing members pivotally mounted on the extension and having ribs received in said groove, and resilient means for embracing the members to maintain the latter engaged with the post.

4. A battery connector including a peripherally grooved post, and a conductor terminal including a conductor end receiving means, post embracing members pivoted on said conductor receiving means having ribs .engaged in the groove of the post, and a spring band removably engaged with the exteriors of said members for holding said members clamped on said post,

5. A battery connector including a peripherally grooved post, and a conductor terminal including a pair of pivotally connected post embracing arcuate members having interior ribs engaged in the groove of the post and having exterior grooves, a conductor supporting means carried by the pivot means and engaged in the groove of the post, and a spring band removably engaged in the exterior grooves of the members.

6. A battery connector including a conductor end supporting means, a lug formed on said supporting means, arcuate battery post embracing members connected to said lug, spaced circumscribing flanges on the outer face of each of said embracing members, and a at spring band positioned between said flanges and embracing said embracing members, said spring band having outturned ends forming finger means to facilitate the removal thereof.

'7. A battery connector including confductor Vend supporting means, battery post embracing members projecting laterally from said ,supporting means, one end of eachV of said members being pivoted to said supporting means, and a vspring band embracing said post embracingi members.

8. A battery connector including a conductor end supporting means, a lug formed on said supporting means, arcuate battery post embracing members pivoted to said lug, spaced circumscribing flanges on the outer face of each of said embracing members, and a flat spring band posi.. tioned between said anges and embracing said embracing members, said spring band having outturned ends forming nger means to facilitate the removal thereof.
